LOOM non WEAVING.

Application filed February 18, 1925, Serial No. 9,510, and in GermanyFebruary 13, 1924.

This invention relates to improvements in weft inserting mechanism forlooms for weaving of the type in which the weft is inserted half waythrough the shed by means of a weft rod or needle and taken theremainder of the distance by means of a hook device. 1

According to this invention a combined weft insertion and withdrawingrod is arranged at both sides of the loom so that a weft thread can beinserted double from either side of the shed to the centre and withdrawnfrom the other side after the portion attached to the end of theprevious pick has been cut.

Owing to the fact that the weft is inserted in a given rotation asdesired from both sides of the weave, a firm edge and a regularly boundselvedge of fabric can be made for any combination. For instance, whenusing a simple linen'binding it is advisable to insert the weft in theproportion of 2:2, i. e. from each side two wefts one after the otherare inserted, with the result that each weft inserted from the same sidewill lie in a different shed and engages the most extreme warps.

Through this invention it is further possible to weave in multi-colors anumber of patterns by using two bobbins with differently dyed weftmaterial, inasmuch as according to the pattern as many wefts areinserted from one side as correspond to the requirements.

In order to enable the feeders to carry out their task in a regularmanner, the insertion devices consist of a combined fork and hook, sothat according to the work desired each weft insertion device may serveas weft feeder or remover. In order to prevent any loose warp threadsfrom being caught on the entry of the new insertion device in the shapeof a fork and hook, the latter is provided with protecting contrivanceswhich divide the warp threads.

One form of the invention is illustrated in the accompanying drawing vizFig. 1 shows the front view of the right side of a loom with the weftinserting device for one feeder and bobbin;

Fig. 2 shows the side of the slay, partly in section, from which can beseen the working operation of the thread feeder;

Fig. 3 is a modification of the arrangement shown in Fig. 2 showing apattern chain for operating the thread feeder.

Fig. 4 shows a front view of the upper part'of the weft feeder with thefront parts, in the shape of fork and hook, of the weft insertiondevice.

Fig. 5 is a section through the insertion device.

Fig. 6 is a plan view of the upper part of,

from below of part of Fig. 4.

Fig. 8 is a side view of part of Fig. 7; and

Fig. 9 is a plan similar to Fig. 7 showing the hooks 23 in the centre ofthe shed and with the protecting device or warp divider 25 in section.

The loom operates as follows The rotating shaft 1 drives, through thechain 4; and chain wheels 2 and 3, the shaft 5 on which latter a patterndisc 6 is fixed. The disc 6 by means of the lever 7, runner 8. and thebracket 9 lifts at the moment of the impact of the reedthe thread feeder10, which is bent at right angles at the top 11 and is connected to slay12 at 13, so that the warp feeder will take the position shown in dottedlines in Fig. 6. Normally the weft 15 extends from the bobbin at aparticular side of the loom through the eyes 16, 17 direct to the fellof the cloth as shown at 20, Fig. i in which position it does not lie inthe path of the inserter 22.

When it is desired to insert a weft however, from this particular sidethe feeder 11 is raised at the beat up so as to pass over the weft 20when the slay moves back from the dotted line position Fig. 6, to thatshown in full lines. The feeder is then moved down taking with it theweft 2O into the position 20, 20 where it lies in the path of theinserter 22. Accordingly therefore as the feeder 11 at a. particularside is, or is not operated, a weft is or is not inserted from this sidewhen the inserting device 22 moves inwards.

When the insertion device 22, acting in part 20 of the weft thread 20lies in i 20 along with it in the Well-knownmanner as described in myprior British specification No. 204,143.

In order to prevent any loose Warp'threads, Which may be hanging down,from being damaged by the insertion device t-he latter isprovidedwith aprotector 24, ending in point 25 by which "the Warp threads are divided.

In orderto have the feeders Workingin the desired rotation, 'the'pattern disc or dobby, which Works the feeders, is providedWVltlLSeVeIELl studs, 26 and 27. Itais of course necessary that theshaft 5 stand in the correct rat1o'ofgear to the inserting devices. Inorder to give a greater range of patterns, a pattern chain with studsorta-ppets 28 may be used, as shown in Fig. 3.

It is of course necessary thatthesame arrangement should exist onbothsides of the machine.

What I claim as my invention and desire to protect by Letters Patentis 1. lVeft inserting mechanism for looms for Weaving of the typereferred to comprising 'at both sides ofthefloom a combined Weftinsertion and Withdrawing rod; a sliding rod to bring the'weft into thepath of the in serter and a pattern chain for controlling -the movementof the sliding rod.
